Autoplot Application (20200327a)
PNG with plotInfo for a log y-axis was handled incorrectly. Here the white line is a plot of the data on top of an plot image of the data.
Autoplot allows plotting of data from many data sources, including remote CDF files and OpenDAP servers.
Datasets are identified with URIs, and by the URI's extension, data are loaded into the internal data model. Data are then
displayed by guessing the rendering method and axis ranges to provide a reasonable, useful view of the data. Data can then
be additionally processed with other operations like smooth and FFT, and Jython scripting provides a capable programming environment.
This is the Autoplot v2020a branch. This is an update to the production version containing bugfixes and minor new features.
Java 7 is now required. Java 8 will be required sometime soon.
Run with 4GB of memory (64-bit Java only): autoplot_4GB.jnlp
Single-jar version, autoplot.jar, can be run without network access and from the command line.
Mac DMG Release is available.
Bugfixes (2020-03-24 r24707):
- AutoplotServlet uses https for third-party codes, so the thin client works again.
- LeafTrim didn't slice the properties properly, dropping DEPEND_1 when the vertical slice was used with spectrograms from AsciiTableDataSource. Thanks, Bill!
- AsciiParser had some path which would result in a parsable line but then would fail to create a DelimParser. Thanks, yumin!
- 714: corrections to yaxis locations for each pixel row.
- 2255: rfe711 was incorrectly implemented when appending two datasets. Thanks, Ivar!
- 0484: improve support for guessing aggregations, by looking at extent of digits and for constant digits. Thanks, Mike!
- 1146: condition where flipped axes and no yTagWidth guess would cause index out of bounds. Thanks, Mike!
- 715: waveform data can contain TT2000 timetags for DEPEND_1, supporting Parker Solar Probe groups.
- NetCDF variable attributes are visible in USER_PROPERTIES, and long_name is used for label when nothing else is available.
- NetCDF GOES n,3 arrays are rendered as X,Y,Z components to match CDAWeb logic.
- ASCII table GUI allows selection of values to use for y-tags (depend1Values keyword). Thanks, Bill!
Less recent features:
- 714: other improvements to image data source, like showing plot titles in completions.
- 698: support read of old Matlab .mat files, containing rank 1 or rank 2 data and structures and datetime arrays. Thanks, Chris!
- 714: ImageDataSource clip=T switch allows aggregation of images containing plotInfo.
- 713: GitHub support now supports branches.

- Features typically have a three-digit ID and can be reviewed with https://sourceforge.net/p/autoplot/feature-requests/<ID>/.
This completes the feature set for the new production branch. No major features will be added before branching this version.
A production branch will be started in a couple of weeks, and the "Start Autoplot" link at the top of
autoplot.org will run this version.
Feedback on the function and quality of this release is greatly appreciated!

- Excel spread sheets (.xls)
- das2Streams (.d2s or .das2Stream)
- ViRBO's TSDS server

This is not complete, and limitations include:
- Quantities of rank 3 dimensionality (e.g. flux(Time,Energy,pitch) are plotted by slicing.
- Quantities of rank 4 dimensionality (e.g. flux(Time,Energy,azimuth,sector) are plotted by slicing twice.
